About AirCaption
AirCaption is desktop software for Mac and Windows that turns audio and video into captions, transcripts, and subtitles. According to its homepage, speech recognition runs on the user's machine using NVIDIA, Cohere, or Whisper models. Users can review and correct text and timing, translate subtitles, and export SRT or VTT files, a plain transcript, or captions burned into the video.
The homepage states that processing is private by default and that nothing is uploaded unless the user chooses it. Cloud translation is optional. It offers more languages and faster turnaround, and it sends only the selected caption text. Pricing is not stated in the source.
